There are several possibilities. The first thing I would check is the Control Unit Seat Heater (Relay) under the seat. You could swap the relay from the passenger seat since you know that works. You can also swap the switches from the passenger to the driver's seat to rule out a problem with the switch.

This article on retrofitting OEM seat heaters contains detailed information including diagrams and part numbers regarding the design and operation of the seat heaters: http://www.dennisvogel.com/heatedseats/index.html
